Packers quarterback Aaron Rodgers, who underwent surgery Thursday to repair his broken right collarbone, posted a post-operative photo on Instagram, flashing a hang-loose sign from a hospital bed, saying the "surgery went well" and thanking fans for their support.

He closed the caption with the hashtags #comebackstartsnow and #riseagain.

Rodgers was injured on Green Bay's second possession of last Sunday's 23-10 loss to the Vikings. He was hit by Vikings linebacker Anthony Barr and driven into the turf at U.S. Bank Stadium as he threw a pass to tight end Martellus Bennett.

Packers coach Mike McCarthy said Monday that Rodgers would undergo surgery this week. The procedure, which was first reported by NFL Media, could keep him out for the season. The Packers have not yet placed Rodgers on injured reserve, hoping he could return by the end of the season.
